But nonfunctional requirements such as reliability, performance and security are still extremely hard to get right, because they not only need code but many correct organizational decisions to be achieved.
As customers connect these nonfunctional requirements with a brand, I don't see how big SaaS players will have a problem.
For new brands, it's as hard as ever to establish trust. Maybe coding is a bit faster due to AI, but I'm not yet convinced that vibe coders are the people on top of which you can build a resilient organization that achieves excellence in nonfunction requirements.
